Abstract
Systems and methods for controlling vacuum within phacoemulsification systems are described. The phacoemulsification system may include a handpiece having a needle coupled to a power source configured to cause the needle to be ultrasonically vibrated, and an aspiration source. The system further includes a footpedal that defines a first position and a second position and a computer program product, operatively coupled to the handpiece and the footpedal, having a non-transitory computer-usable medium having a sequence of instructions which, when executed by a processor, causes the processor to execute a process that controls power from the power source and vacuum from the aspiration source applied to the handpiece.
